HARQ feedback transmission
A wireless device may receive one or more messages. The one or more messages may comprise configuration parameters of a first uplink control channel and a second uplink control channel. Downlink control information may be received. The downlink control information may indicate a downlink transmission of a transport block via a downlink channel. One of the first uplink control channel or the second uplink control channel may be selected as a selected uplink control channel based on one or more parameters of the downlink control information. A hybrid automatic repeat request (HARD) feedback for the transport block may be transmitted via the selected uplink control channel.
1. A method comprising:
transmitting, by a wireless device and to a base station, a capability message indicating a physical uplink control channel (PUCCH) switching capability of the wireless device;
receiving, based on the PUCCH switching capability, one or more messages comprising configuration parameters of a first PUCCH and a second PUCCH of a cell group;
receiving downlink control information (DCI) indicating a downlink transmission of a transport block;
selecting, a field of the DCI, a PUCCH from the first PUCCH and the second PUCCH of the same cell group; and
transmitting a hybrid automatic repeat request (HARQ) feedback for the transport block via the selected PUCCH.
2. The method of claim 1 , wherein:
the DCI is received via a downlink channel; and
one or more parameters of the DCI indicate a numerology of a carrier of the downlink channel.
3. The method of claim 2 , wherein the first PUCCH has a first format and the second PUCCH has a second format.
4. The method of claim 2 , wherein the first PUCCH corresponds to a first duration and the second PUCCH corresponds to a second duration.
5. The method of claim 2 , wherein the configuration parameters indicate first radio resources for the first PUCCH and second radio resources for the second PUCCH.
6. The method of claim 1 , wherein one or more parameters of the DCI indicate one or more logical channels, wherein data of the one or more logical channels are multiplexed in the transport block.
7. The method of claim 6 , wherein:
the DCI is received via a downlink channel;
the DCI comprises a value indicating a timing between the downlink channel and the HARQ feedback;
the HARQ feedback is transmitted via the selected PUCCH in a first slot; and
the first slot is based on the value and a numerology of the selected PUCCH.
8. The method of claim 1 , wherein one or more parameters of the DCI indicate a size of the transport block.
9. The method of claim 8 , wherein the first PUCCH corresponds to a first duration and the second PUCCH corresponds to a second duration.
10. The method of claim 8 , wherein the configuration parameters indicate first radio resources for the first PUCCH and second radio resources for the second PUCCH.
11. The method of claim 1 , wherein the first PUCCH has a first format and the second PUCCH has a second format.
12. The method of claim 1 , wherein the first PUCCH corresponds to a first duration and the second PUCCH corresponds to a second duration.
13. The method of claim 1 , wherein the configuration parameters indicate first radio resources for the first PUCCH and second radio resources for the second PUCCH.
14. The method of claim 1 , wherein:
the DCI is received via a downlink channel;
the DCI comprises a value indicating a timing between the downlink channel and the HARQ feedback;
the HARQ feedback is transmitted via the selected PUCCH in a first slot; and
the first slot is based on the value and a numerology of the selected PUCCH.
15. The method of claim 1 , wherein:
a first cell, of the cell group, is configured with the first PUCCH; and
a second cell, of the cell group, is configured with the second PUCCH.
16. The method of claim 1 , wherein the cell group is a PUCCH group.
17. The method of claim 16 , wherein:
a first cell, of the PUCCH group, is configured with the first PUCCH; and
a second cell, of the PUCCH group, is configured with the second PUCCH.
